Survey Data

A shoreline plant survey was conducted during the last two weeks of June 2001. Sites were selected every 30 ft. on a North South transect along the shoreline beginning 20 ft. from the North end of the park and ending directly East of the old red barn. The survey was conducted from the cropline to 20 ft. out into the lake.

ABIOTIC DATA

water clarity	1.5 ft secchi disk	total chlorine	0ppm
temperature	79.4 F 26.2 C	free chlorine	0ppm
pH	8	total hardness	250ppm
dissolved oxygen	12 9	total alkalinity	200ppm

Dissolved oxygen

The higher number the better the quality of the water.
Decaying organic matter, from runoff, algae, waste, etc., uses up the dissolved oxygen.
Sufficient purity for recreation is 7-8 parts per million (7-8mg/liter)

Greater than 68 degrees	Much plant life; many fish diseases; most bass, crappie, bluegill, carp, catfish; caddisfly
55-68 degrees	Some plant life; some fish diseases; salmon, trout; stone fly, may fly, caddisfly, water beetles, striders
Less than 55 degrees	Trout; caddisfly, stone fly, may fly.

pH Ranges That Support Aquatic Life

bacteria can survive 1.0-13.0
plants can survive 6.5-12.0
carp, suckers, catfish, some insects 6.0-9.0
bass, crappie 6.5-8.5
snails, clams, mussels 7.0-9.0
